Hi Matt,
By defining a method like below in your action bean...
public getControlGroupClass(String field) {
// checks the field status and returns an appropriate css class.
return getContext().getValidationErrors().containsKey(field) ? " error"
: "" ;
}
...you can write the outmost div as follows (JSP 2.1+ required).
<div class="control-group
${actionBean.getControlGroupClass('inputWarning')}">

Iwao

> An example of a field with a validation error is:
>
> <div class="control-group warning">
> <label class="control-label" for="inputWarning">Input with
> warning</label>
> <div class="controls">
> <input type="text" id="inputWarning">
> <span class="help-inline">Something may have gone wrong</span>
> </div>

> There's two things to note here:

> field-level validation today, it just goes in as an entry in the

> 2.) There's an extra class added to the outmost enclosing div (it goes
